A steel wire 0.72 m long has a mass of `5.0 xx10^(-3)` kg. If the wire is under a tension of 60 N, what is the speed of transverse waves on the wire ?

Text Solution

Verified by Experts

Mass per unit length of the wire
`mu=(5.0xx10^(-3)kg)/(0.72m)=6.9xx10^(-3)kgm^(-1)`
Tension, `T=60N`
the speed of wave on the wire is given by `v=sqrt((T)/(mu))=sqrt((60N)/(6.9xx10^(-3)kgm^(-1)))=93 ms^(-1)`
